Preoperative Cardiovascular Assessment of the Renal Transplant Recipient: A Narrative Review.

Patients with end-stage kidney disease (ESKD) have a high prevalence of cardiovascular disease; it is the leading cause of death in these patients and the optimisation of their cardiovascular health may improve their post-transplant outcomes. Patients awaiting renal transplant often spend significant amounts of time on the waiting list allowing for the assessment and optimisation of their cardiovascular system. Coronary artery disease (CAD) is commonly seen in these patients and we explore the possible functional and anatomical investigations that can help assess and manage CAD in renal transplant candidates. We also discuss other aspects of cardiovascular assessment and management including arrhythmias, impaired ventricular function, valvular disease, lifestyle and pulmonary arterial hypertension. We hope that this review can form a basis for centres hoping to implement an enhanced recovery after surgery (ERAS) protocol for renal transplantation.

Gender Disparity in Abstract Presentation at Plastic Surgery Meetings.

BACKGROUND: Medical and surgical fields continue to be marred by gender disparities. The "leaky pipeline" effect, representing a gradual decline in female representation along the academic ladder, has been well documented in plastic surgery. However, gender differences in abstract presentation at national plastic surgery meetings and subsequent publications remains elusive. METHODS: We reviewed abstracts presented at the 2014 and 2015 annual meetings of the American Association of Plastic Surgeons (AAPS); American Society of Plastic Surgeons (ASPS), and the Plastic Surgery Research Council (PSRC). Several abstract characteristics including the names of the first and last authors were extracted. Genderize.io and Google search were used to identify the authors' gender. RESULTS: We identified 1174 abstracts presented at the three identified meetings. Females comprised 29% of the presenters and 16% of abstract senior authors (ASAs). No gender differences were identified between the meetings, type of presentation (oral versus poster), and year of presentation. The only difference was in the subspecialty of the abstracts. Successful conversion to full-text articles was similar for male and female presenters (68% versus 62%, P = 0.065) but higher for male ASAs (68% versus 59%, P = 0.01). When an author change occurred, female presenters and ASAs were more likely to be replaced by males (P < 0.001). CONCLUSION: Gender differences continue to be evident in academic plastic surgery with women constituting a minority of both presenters and senior authors on abstracts presented at national plastic surgery meetings. Future work should assess whether flexible and supportive work policies can foster greater female representation in academic plastic surgery.

Assessment of human leukocyte antigen immunogenicity: current methods, challenges and opportunities.

PURPOSE OF REVIEW: Donor-recipient human leukocyte antigen (HLA) matching improves outcomes after solid-organ transplantation, but current assessment of HLA incompatibility is inadequate as it does not consider the relative immunogenicity of individual HLA mismatches. In this article, we review existing strategies for assessing HLA immunogenicity and discuss current challenges and future opportunities in this field. RECENT FINDINGS: Current HLA immunogenicity algorithms focus primarily on the humoral component of the alloimmune response and aim to determine a measure of 'dissimilarity' between donor and recipient HLA. This can be achieved by deriving information from comparison of donor and recipient HLA at the amino acid sequence, structural and/or the physicochemical level, accounting for both B-cell and T-cell pathways of alloreactivity. Substantial evidence now supports the superiority of this molecular definition of HLA incompatibility, over conventional enumeration of HLA antigenic differences, for assessing the risk of humoral alloimmunity and for predicting graft outcomes after transplantation. SUMMARY: Significant progress has been made in developing computational HLA immunogenicity algorithms that offer exciting opportunities for a more rational approach to determining the degree of donor-recipient HLA incompatibility and to defining HLA-related immunological risk. A number of challenges now need to be overcome to enable their implementation into clinical practice.
